It accepts a J-type shank measuring 0.425 inches and delivers a maximum torque of 60 foot-pounds, making it suitable for controlled torque application where an open-end profile is required to access fasteners that a standard closed socket cannot reach. The center-of-fastener to retaining pin measurement is 2.5 inches. At 0.14 pounds, it is a lightweight accessory that attaches to a compatible torque wrench drive. Licensed mechanics, HVAC technicians, plumbers, and pipefitters use this type of head when torque specifications must be met on hex fasteners in confined or offset locations.\u003c\/p\u003e\u003cp\u003eThis torque wrench head is suited for SAE fastener sizes in residential and commercial service environments. It is particularly useful when working on refrigerant line fittings, gas connections, or mechanical assemblies where a specific foot-pound value must be achieved and verified. The open-end head style allows engagement on fasteners that are partially obstructed or installed in tight clearance areas where a box-end or socket-style head would not fit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8 inch open-end head size for SAE fasteners\u003c\/li\u003e\n\u003cli\u003eMaximum torque rating of 60 foot-pounds\u003c\/li\u003e\n\u003cli\u003eJ-type shank with 0.425 inch shank diameter for compatible torque wrench drives\u003c\/li\u003e\n\u003cli\u003eCenter-of-fastener to retaining pin distance of 2.5 inches\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.14 pounds for reduced hand fatigue during repeated use\u003c\/li\u003e\n\u003cli\u003eSAE specification for use with standard inch-measurement fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with J-type shank torque wrench drives accepting a 0.425 inch shank.

Ensure the torque wrench drive is set to the required foot-pound value before applying load, and confirm the shank is fully seated and the retaining pin is engaged before use. Do not exceed the 60 foot-pound maximum torque rating. Consult applicable mechanical codes and equipment manufacturer specifications for required fastener torque values.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Open End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 0.425 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Torque\u003c\/strong\u003e: 60 foot-pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter of Fastener to Retaining Pin\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Standard\u003c\/strong\u003e: SAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILLIAMS COMFORT PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QJO20A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51343011447090,"sku":"QJO20A","price":95.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310544242.jpg?v=1782013718","url":"https:\/\/voomisupply.com\/products\/williams-comfort-products-qjo20a-torque-wrench-head","provider":"Voomi Supply","version":"1.0","type":"link"}
